The diagram below represents the fate of a typical crude oil spill, showing changes in the relative importance of weathering process with time (from hours to The aim of present paper was to model and analyze effects of initial oil properties on its behavior, immediately after the spill. For this purpose three different 15 Jun 2013 Discuss the weathering characteristics of spilled oil in the natural coastal zone environments of Dalian Bay. •. Determine the effects of natural When oil spills, the physical and chemical characteristics of oil interact with the physical and biochemical features of the habitat where a spill occurs. The weathering of crude oil involves evaporation or volatilization, These emulsions significantly change the properties and characteristics of spilled oil.

ADIOS® (Automated Data Inquiry for Oil Spills) is NOAA's oil weathering model . It's an oil spill response tool that models how different types of oil weather ADIOS quickly estimates the expected characteristics and behaviour of spilled oil.

A model is proposed to describe the weathering of oil spills taking into account the spreading determined by the physico-chemical properties of the oil and is.

Enbridge 2018 crude oil characteristics. Click here to view the 2018 Crude Characteristics Booklet, a summary of selected chemical and physical properties of crude oils and condensates moved in the Enbridge Pipelines Inc. (Enbridge)/Enbridge Energy Partners, L.P. system. Weathering experiments under natural conditions were performed after Dalian oil spill accident on July 16, 2010. The weathering effects on n-alkanes, biomarkers and polycyclic aromatic Characteristics of Crude Oil •The hydrocarbons in crude oil can generally be divided into four categories: •Paraffins: These can make up 15 to 60% of crude. •Paraffins are the desired content in crude and what are used to make fuels. •The shorter the paraffins are, the lighter the crude is. Many types of crude oil are produced around the world. The market value of an individual crude stream reflects its quality characteristics. Two of the most important quality characteristics are density and sulfur content. Density ranges from light to heavy, while sulfur content is characterized as sweet or sour. Crude oil, and refined products, in the marine environment are subject to physical, chemical, and biological processes that change their composition and environmental impact. The weathering of crude oil involves evaporation or volatilization, emulsification, dissolution, and oxidation (chemical, photo-, and microbial). FIGURE 2-1 Components of typical crude oils.. are attributable mainly to the great influence of biodegradation on the heavier crude oil and bitumen. Saturated Hydrocarbons. Under the anaerobic conditions prevailing during formation of the oil sands, the saturated hydrocarbons are mostly biodegradable, the aromatic hydrocarbons much less so, and the resins and asphaltenes not at all.

The suitability of in situ burning depends on the initial oil characteristics and the weathering state of the oil. Several factors are important for a successful burning:.

1 Mar 2013 Oil weathering models predict the changes in oil characteristics – evaporate, emulsify and disperse into the water column. The changes may Spill models are used to predict the physical and chemical properties of weathered oil, the location of spilled oil at a particular time, and the oil mass balance The sum of these physical and biological processes results in what we call "weathering" of the oil, reflected in the changes in chemical composition and physical characteristics over time. The more closely the chemical composition of an oil residue resembles that of the unspilled source oil, the "fresher" it is. Compounds present in crude oil (a) and 120 days after spill (b). Figure 4. Isotopic profile of oil compounds. A combination of crude oil and all residue samples up to 120 days after spill, demonstrating the conservation of original signature. Conclusion Classification of crude oil types by geographical source is generally not a useful classification scheme for response personnel because they offer little information about general toxicity, physical state, and changes that occur with time and weathering. These characteristics are primary considerations in oil spill response.

The Automated Data Inquiry for Oil Spills (ADIOS2) software is an oil weathering model provided by NOAA that incorporates a database containing more than a thousand crude oils and refined products, and provides quick estimates of the expected characteristics and behavior of oil spilled into

These characteristics were computed for fresh and weathered petroleum. 1. Introduction. Numerous investigations have confirmed the harmful influence of. Weathering Processes in the DHI Oil Spill Model . Physical Properties of Oil . to obtain the characteristics for the composition used in the DHI oil weathering. have well-defined properties irrespective of the crude oil from of the fate of a crude oil spill showing changes in the relative importance of weathering.
